Title: High concentration no pulse delivery device
Inventor: BATHE DUNCAN P L
IPC: A61M16/06
Filed: 1999-05-17
Granted: 2008-08-05
Abstract: A respiratory therapy apparatus that delivers a predetermined pulsed dose of a therapeutic gas to a patient upon inhalation of the patient. The system has separate conduits for the supply of the therapeutic gas at a high concentration and for the supply of a diluent gas. The therapeutic gas conduit has a control valve that is accurately controlled to open and close so as to deliver a precise dose of the high concentration therapeutic gas. The diluent gas conduit has means to ensure there is a sufficient flow of diluent gas to ensure the said high concentration therapy gas is diluted to a safe concentration. A third conduit receives the gasses from both the first and second conduits to that the gasses are mixed together and administered to the patient. By this system, the therapeutic gas supply can be of a high, otherwise harmful, concentration and the therapeutic gas is diluted prior to introduction to the patient. The therapeutic gas may be nitric oxide and the diluent gas may be nitrogen or an oxygen containing gas.

Abstract: La présente invention concerne un procédé pour évaluer des paramètres de qualité et de quantité de particules biologiques dans un mélange liquide à analyser. Ce procédé consiste à appliquer un volume d'un échantillon liquide à un domaine d'exposition à partir duquel les signaux électromagnétiques provenant de l'échantillon dans le domaine peuvent passer vers l'extérieur, et exposer, sur un ensemble d'éléments de détection actifs tels que des éléments à couplage de charge, une représentation spatiale des signaux électromagnétiques provenant du domaine. Cette représentation peut être détectée sous forme d'une intensité par des éléments de détection actifs individuels, dans des conditions permettant de traiter les intensités détectées par l'ensemble d'éléments de détection pendant l'exposition, d'une manière permettant de représenter les signaux électromagnétiques provenant des signaux de fond. La taille du volume de l'échantillon liquide est suffisamment importante pour permettre d'évaluer les paramètres de quantité et de qualité pour respecter une exigence prédéterminée en matière de qualité statistique de l'évaluation, sensiblement en fonction d'une exposition.

Granted: 2004-08-03
Abstract: Modular terminals for supplying conditioned air to spaces within buildings can be mounted and configured to provide improved heating, cooling, ventilation, and mixing of the supplied air with the space air. The flexibility in arranging the modular terminal components, such as air inlets, outlet grilles, dampers, and induction sleeves, permits for selectively altering the flow pattern, quality, volume, and velocity of air introduced into a space.   The modular terminals can selectively draw air from a plenum, duct, or both.     The terminals accommodate electrical wiring for office equipment, and also may accept flexible ducting to deliver conditioned air from a desktop or other furniture. The modular terminals also are part of a system and method for conditioning building spaces whereby a number of terminals are controlled in response to selected sensor readings. Various air handling units combine with the terminals to cycle the air and supply a source of filtered and conditioned air to the terminals.

Title: Data transfer request processing scheme for reducing mechanical actions in data storage system
Inventor: KANAI TATSUNORI
IPC: G06F3/06
Filed: 2000-03-23
Granted: 2006-08-08
Abstract: If an accepted data transfer request includes a deadline for completing requested data transfer, a time earlier than the deadline by a properly predetermined period is set as a class switching time for the accepted data transfer request. The accepted data transfer request is repeatedly checked and then classified into the second class if a current time has not yet passed the class switching time and classified into the first class if the current time has passed the class switching time. The first class employs a scheduling policy in which a completion of each data transfer within a deadline specified for each data transfer request is a primary key factor in determining an order of processing. The second class employs another scheduling policy in which a reduction of amounts of the mechanical actions required in carrying out each data transfer is a primary key factor in determining an order of processing. Basically, first class data transfer requests are processed at higher priority than the second class data transfer requests.

Title: Information delivery in a multi-stream digital broadcasting system
Inventor: NORR WILLIAM M
IPC: G10L19/00
Filed: 2000-07-25
Granted: 2005-01-04
Abstract: Audio or other information is delivered to a user via a multi-stream digital broadcasting system in a partially-encrypted form. The information is encoded and separated into multiple bitstreams, at least a subset of which are left unencrypted. Both the encrypted and unencrypted bitstreams are received and stored by the user. A  user is able, for at least a limited period of time, to access the information at a first quality level, e.g., an FM-quality level for audio information, without having the corresponding decryption key, by utilizing only the unencrypted bitstreams. The user can then access an electronic-commerce web site to purchase the decryption key. The key may be downloaded from the site to an information processing device of the user, and may be utilized to decrypt the partially-encrypted format, such that the user is provided with access to the information at a second quality level higher than the first quality level, e.g., a CD-quality level for audio information. The multiple bitstreams may correspond, e.g., to subbands of at least first and second digital sidebands of a host carrier signal in an FM in-band on-channel (FM-IBOC) digital audio broadcasting system.

Abstract: A fiber planted steel sheet obtained by forming only a fiber planting layer having excellent adhesion to a substrate made from a composition having special composition on the surface of a surface treated steel sheet as a substrate without forming a primer of a polyester synthetic resin containing an anticorrosive pigment and the like and electrostatically planting short fibers in the planting layer. Therefore, the electrostatically fiber planted steel sheet is produced by coating an aqueous adhesive composition for planting fibers comprising an emulsion resin having a glass transition temperature of -40 to 40 °C, aqueous coloring pigment dispersion, defoamer and pH modifier on the surface of the surface treated steel sheet to form a fiber planting layer having excellent adhesion to the steel sheet on the surface of the steel sheet and electrostatically planting short fibers while the surface of the planting layer retains adhesion.

Abstract: Through holes (3a) are made in the side wall of a base (3) of an embedded-type light (1). Ends (6a, 7a) of reinforcing steel bars (6, 7) of an RC pavement (2) laid around an embedded portion of the light are inserted into the through holes (3a), and the rims of the through holes (3a) are firmly secured to the ends (6a, 7a) of the reinforcing steel bars (6, 7) by welding. Therefore, the load exerted from above on the light (1) is distributed not only to the portion of the RC pavement (2) in contact with the lower surface of the base (3) but also to the reinforcing steel bars (6, 7), so that the punching shear resistance of the RC  pavement (2) is significantly improved. Thus, an embedded-type light which does not cause a dent in an RC pavement under the base of the light even if a heavy load such as an airplane is exerted is realized.

On combine différents maillag es chacun avec ses propres méthodes de formation, de représentation et d'exploration, des maillages structurés avantageux en ce qu'ils facilitent le contrôle et la compréhensio n des images que l'on forme du gisement et des maillages non structurés plus souples pour réaliser le maillage des zones complexes. - Applications à des simulateurs de gisements d'hydrocarbures par exemple.</ SDOAB>
